There are two issues here. One is which, if any, versions of IOS for
the 1600 platform support BGP.
Second, if the goal is to learn BGP, there is no benefit to having a
full routing table. What are you going to do with it? Inspect every
line? To put this into perspective, and rounding off a bit, the
default-free routing table has around 100,000 routes in it. A tier 1
provider will have an additional
30,000 or so customer and internal routes.
Many of these routes (remember, in BGP speak, a route is a
destination) will have four potential paths to use. Depending on the
number of peers, there may be appreciably sized views that differ per
peer or per peer group.
Even in operational practice, full routes aren't always necessary.
Depending on the policies in effect, you might want to see only
customer routes of your provider, or routes that belong to some
community, etc.
